In the accompanying drawings in which is illustrated the preferredembodiment of the invention as applied to a railway crossing 1designates rails arranged in pairs at right angles to each other andconnected at their ends to corner bearing plates 2 each is adiagrammatical view, illusing plates. The inner attaching meanscomprises lugs or flanges 4 and arranged in pairs and spaced apart toreceive the web 6 of the rails 1 which are sheared off at theirends toform projecting bottom flanges 7 that extend into recesses 8 of thecorner bearing plates.

The projecting flanges 4 and 5 which are approximately inverted L-shapedin cross section as clearly illustrated in Fig. 3 of the drawings areriveted or otherwise secured to the webs 6 of the mile 1 against whichthey are fitted. The outer attaching means for securing the outer railsections 3 to the corner bearing plates consist of progecting flanges 9and 10 spaced apart to receive the webs of the rail sections which aresheared off to leave projecting bottom flanges 11 for extending intoouter bottom recesses 12 of the bearing plate 2. i The flanges 9 and 10are substantially the same as the flanges 4. and 5 with the exceptionthat the latter are slightly longer than the outer projecting flanges 9and 10. The corner bearing plates extend over the projecting bottomflanges of the rails 1 and 3 and the said rails are connected at each ofthe corner bearing plates by a bottom connecting plate 13 to which thebottom flanges of the said rails are riveted or otherwise secured. Theprojecting flanges of the corner plates are cut away at 14 to aflordaccess to the rivets 15 or other fastening devices and after the 1 partshave been assembled filler blocks 16 are secured in the said recesses 14as clearly illustrated in Fig. 2 of the drawings. Each of the connectingplates 13 is arranged upon a tapered or beveled compression plate 17interlocked with the corner bearing plate and connecting plate by pins18 arranged vertically and piercing the projecting bottom flanges of therails, the connecting plate 13 and fitted in sockets 19 and 20 in thecorner bearing plates and the compression plate. The base'or compressionplates 17 are riveted or otherwise secured to tie bars 21 extendinglongitudinally of the rails 1 from one point of intersection to theother and fastened at intervals to the bottom flanges of the said railsby rivets 22 or other suitable fastening devices and also secured to thesaid rails and the connecting plates by the rivets 15. The rivets 23which pierce the crossed or overlapped ends of the tie plates or bars 21and the base plates 17 have their heads countersunk in the latter asclearly as shown in Fig. 2 of the drawings. Any other suitable fasteningmeans may of course be employed for securing these parts together. Theterminal portions'of the tie bars or plates 21 are angularly bent asshown at 24 to conform to the configuration of the beveled edges of thebase plate 17 and the construction forms a solid truss like structureand rigidly connects the parts together so that it is unnecessary toplace a tie ,or similar support under the adjacent ends of the rails ofthe crossing. The corner bearin plate is of irregular rectangular shapean the bottom connecting plate which extends outwardly beyond the sidefaces of the corner bearing plate is provided in its projecting portionswith spike receivmg recesses or openings 25 for the reception ofsuitable fastening means for securing the crossing in position. Thecrossing is provided at each of the rails with a flange way or groove 26formed by longitudinally disposed guide plates 27 preferably arranged inpairs and connected by an angularly disposed portion 28 fitted againstthe adjacent side face of the corner bearing plate. The guide plateswhich are spaced from the adacent sides of the rails 1 by filler bars 29preferably extend to the centers of the rails l midway between thecorner bearing plates 2 as clearly shown in Fig. l of the drawings butthe guide plates may be of any desired length as will be readilyunderstood and they are secured to the rails 1 by rivets or othersuitable fastening devices which pass through the guide plates, therails, and the filler bars. The filler bars which are preferably made insections as shown to facilitate casting and assembling the parts areprovided in their bottom faces or edges with recesses or grooves 30 toreceive the heads of the rivets 15 and 22 which secure the tie bars orplates to the bottom flanges of the rails. Guide plates 31 are alsolocated at the other side faces of each of the corner bearing plates asclearly shown in Fig. 1. These plates 31 have terminal attachingportions and angularly disposed connecting portions, the attachingportions being secured to the adjacent rail. The terminal portions ofthe plates 31 form outer. grooves 32 for guiding the flanges of thewheels and the attaching portions of the said plates 31 have the flanges9 interposed between them and the rails.

Each of the corner bearing plates is provided in its upper face with acylindrical bearing recess 01 socket 34: receiving a circular rotaryfrog member 35 provided with a flange way or groove 36 adapted to bearranged in alinement with the flange ways or grooves of theintersecting rails to form a continuation of the grooves or Ways forsafely guiding the flanges of a wheel at the crossing. The rotary frogmember is provided at opposite sides of the groove 36 with tread faces37 which are arranged in the same horizontal plane as the tread faces ofthe heads of the rails and fixed tread plates 38 are suitably secured tothe corner bearing plates and are located between the sheared portionsoi the rails and the rotary frog member as clearly shown in Fig. 2 ofthe drawings. By this construction a conill anai tinuous tread surfaceand a continuous flange way or groove is provided at each intel-sectionof the rails so that all hammering of the wheels of a car or the like atintersecting rails is entirely eliminated.

By this construction all jar, vibration and pounding of the rails at acrossing or other intersection is prevented and in ury to the rails andthe rolling stock from such pounding is eliminated and the cost of theupkeep of a railroad greatly reduced. Each of the rotary frog members isprovided with a con trally arranged depending stem 39 extending througha central vertical opening 40 of the corner bearing plate and piercingthe base plate 17, the connecting'plate and the overlapped terminals ofthe tie plates or bars. The stem is provided at its lower end with athreaded portion 41 to receive a nut i 'diate of their ends with 42 andit has a squared portion 43 on which is mounted a gear element 44. Thegear element which has a rectangular opening 45 to receive the squaredportion 43 of the stem is secured to the latter by a cotter pin 46 andit has an arcuate edge provided with spur teeth 47.

The gear elements 44 of the rotary frogs are actuated by oscillatoryarms or bars 48 and 49 disposed diagonally with relation to the crossingand provided at their outer ends with gear elements 50 and 51. The gearelements 50 and 51 are substantially in the form of racks, the teeth ofthe gear element 50 of the oscillatorybars or arms 48 extendingoutwardly from cnlar ed terminal portions of the said arms or ars. Theother set of arms 49 are rovided intermed flecting bands 52 whicharrange the body portions of the said arms 49 below the plane of theother arms 48 and enable the said arms or bars 49 to extend beneath thestem upon which the coacting. gearing elements are mounted. The arms orbars are provided at their outer ends beyond the stems with verticallydisposed flanges 53 having inwardly projecting spur teeth constitutingthe gear elements 51. The gear elements of the stems contiguous to thegear elements 51 are arranged reversely of the gear elements of theother stems in order to mesh with the inwardly projecting teeth of thegear elements 51 of the arms or bars 49. This arrangement efl'ects arotary movement of some of the frog members clockwise and other of thefrog members counter-clockwise when the arms of bars 48 and 49 areoscillated in the same direction and a different tread surface ispresented to each of the tracks of the inner section so that neither oneof the said surfaces of the rotary frog member is subjected to all ofthe Wear incident to the travel over the crossing, The water collectingin the bearin sockets or recesses 34 is drained from the bysubstantially annular grooves 54 located beyond the bearing faces of thesaid sockets and communicating with a passage 55 having a tapered orflaring outlet and communicating with openings (not shown) in theconnecting plate and the base plate to permit the escape'of the waterdraining from the bearing socket or recess. By this arrangement of thegrooves, the bearing surfaces of the sockets or recesses 34 are notmaterially reduced and a maximum bearing surface is afi'orded.

The inner ends 56 of the oscillatory arms or bars '48 and 49 arearranged in horizontal recesses 57 of an enlarged top supporting portion58 of a vertical rotary support or pivot 59 having upper and lowerjournals or pivot portions 60 and 61 and set in a bearmg 62 of a bottombearing plate 63. The recesses 57 are tapered at their inner ends andthe ends 56 of the oscillatory arms or bars 48 and 49 arecorrespondingly shaped. The side walls of the recesses 57 are extendedabove the upper faces of the arms or bars 48 and 49 and are providedwith undercut or dove-tail grooves 64 which receive tapered laterallybeveled'keys 65 which are secured in interlockedrelation with the rotarysupport or pivot 59 by bolts 66 piercmg the keys the arms orbars 48 and49 and the enlarged upper portion 58 of the rotary pivot or supp courseused. I

The base plate or'bottom bearingqplata ill) throughout the variousportions oflthe con-71 struction but any form of bolt may bg of; act" 68is mounted upon horizontal beams 69 'provided at their end portionswithupwardlyf extending arms 70 arranged verticallyvand provided withoutwardly extending attachiie' ing terminals 71. The outwardly extending7 terminals 71 are secured by suitable fasten? ing devices to the lowerfaces of inwardly proyecting supporting portions 72 0f the contiguousconnecting plate. The upper journal or pivot portion 60 is mounted in anopening 73 of an upper bearing plate'74 and is reduced to form ashoulder 75 which spaces the upper bearing plate from the upper faces ofthe keys '65 which retain the oscillatory arms or bars in the recessesof the pivot or rotary support 59. The upperbearmg plate is bolted orotherwise secured to open approximately rectangular supports 7 6,- eachpreferably consisting of a single piece of metal bent to form spacedsides and a connecting top portion, thelower terminals 77 of the sidesbeing bolted or otherwise secured to the bottom bearing plate 63. Theseopen supports 76 arch the oscillatory bars or its arms 19 and permit thenecessary movement of the latter. The oscillatory arms or bars aresupported at their outer portions by transversely disposed plates 7 8slidably receiving the said arms or bars 48 and secured to the upwardlyextending portlons of the frame bars or members 69 and provided withopposite shoulders 79 which limit the oscillatory movement of the armsor bars.

One of the oscillatory arms or bars as is provided with a thickenedportion 80 having recesses 81 in its lower face and oppositely beveledat 82 at opposite sides of the recesses to present inclined faces to apair of spring actuated latch bolts 83 adapted to lock the oscillatorybars or arms in each of their positions. The recesses 81 are located atopposite sides of the thickened portion 80 of the arm or bar 18 and thevertically movable spring actuated bolts are arranged to engage therecesses 81 when the said arm or bar is at the limit of its oscillatorymove ment. The vertically movable latch bolts are guided in verticallyalined openings 81 and 85 in an approximately inverted U- shaped support86 and a horizontal bar 87 having its terminals 88 bent downwardly andsecured to the inner faces of the sides of the U-shaped support 86. Thelower terminals 89 of the sides of the inverted U- shaped supports arebolted or otherwise secured to the upper face of a transverse supporting plate 90 upon which are mounted vertically disposedelectromagnets 91 adapted when energized to attract armature heads 92carried by the lower ends of the latch bolts and located beneath thetransverse bar 87 as clearly illustrated in Fig. 6 of the drawings. Thelatch bolts are actuated in their upward movement by coiled springs 98interposed between the plate 87 and pins or keys 94 secured againstmovement on the latch bolts by passing through the bolt or othersuitable means, but any other desired form of stop may be employed forengaging the upper ends of the coiled actuating springs. The upperengaging ends of the latch bolts are provided at their inner sides withbeveled faces 95 to enable them to be readily depressed by theoscillatory arm or bar and they also have beveled faces 96 at theirouter sides to enable them to engage or project slightly into therecesses 81 of the oscillatory arm or bar before the latter has reachedthe limit of its movement and the latches will positively engage thesaid arm or bar and efi'ectively prevent the same from accidentallybeing thrown backwardly through contact with the shoulders 79 of theguide plates 7 8. This insures the lock ing of the oscillatory arms inproper position at the end of each movement. The electro-magnets 91which are bolted to the horizontal plate 90 are insulated therefrom bypieces 97 of wood or other suitable material attaching portions 102bolted or otherwise secured to transverse plates 103 and insulatedtherefrom by pieces 104 of wood or other suitable material. Theelectro-magnets 99 are also connected and braced at the back by plates105 having angularly disposed end portions and an integral centralconnecting portion as clearly illustrated. in Fig. 1 of the drawings.The movable electro-magnets are provided with field pole plates 106having upper horizontally disposed attaching portions 107 bolted orotherwise secured to the lower faces of the oscillatory arms or bars 48and insulated therefrom by pieces 108 of wood or other suitable materialand also from the fastening means for securing the parts to theoscillatory bar or member. The field pole plate 106 of the movablemagnet is arcuate and its arc cooperates with the arc of the field poleplate of the stationary magnets so that in the oscillatory movement ofthe arms or bars the field pole plate 106 of the armature movable magnetmoves toward and from the field pole plates of the stationaryelectromagnets which have double windings and which are wound to a northpole and a south pole so that in the operation of the crossing the fieldpole plate of the armature magnets will be repulsed by the field poleplate of one of each pair of stationary electro-magnets and attracted bythe field pole plate of the other electro-magnet.

Mounted upon the inverted U-shaped support 86 are contacts 109 and 110consisting insulators 111. The insulators 111 are secured in suitablesupports or brackets 112 of approximately Y-shape composed of spacedsides and a connecting portion from which depends a centrally arrangedstem. The stem pierces the top of the support 86 and is threaded for thereception of a nut as clearly shown in Fig. 6 of the drawings. Thecontact plates or pieces 109 and 110 which are designed to be connectedwith signal light wires are arranged in pairs at opposite sides of thesupport and the contact plates 110 which are of greater length than thecontact plates 109 are resilient and are adapted to be sprung intoengagement and electrically contact with the plate 109 whereby one ofthesignal light circuits will be closed when the oscillatory bars or armsare in each position.

The thickened portion 80 of the oscillatory arm or bar 48 carries anactuating or circuit pending sides located at the side edges of thethickened portionpf the oscillatory baror member 48 and the said sidesare adapted to flex the contact 110 a. and force the same intoengagement, with the contacts 109.

in one direction by the energizing of, the stationary electro-magnetsand the movable Y electro-magnets the. latch bolts are with? drawn bythe energizing of the latch operating magnets 91 and as soon as thelatter are deenergized by the cutting ofi of the current the springoperates to force the latch bar's upwardly into their engaging position.
